The Crimson Binome
Hero
You could always have the damsel break free and slay her captor prior to the party getting there. If you're going to subvert a trope, then you might as well subvert an entire boss fight.
Are you playing this thread straight, and are trawling for ideas, or is this very thread subverted, and you are indeed trolling for ideas...?
So my group is going through Against the Cult of the Reptile God and will (likely) soon embark on an investigation of the corrupted temple full of evil cultists. Near the end of the area is a fairly critical NPC woman imprisioned and abused by the head (male) cleric. It's rightfully creepy and the adventure definitely suggests she'll take any opportunity given to attack her captor.
Problem is... The party recently rescued a young halfling girl from a yucky, obsessive, hugging, shaving-her-head-and-blood-painting-her-face kobold (the party let her loose on him later and she face-stabbed him).
So... while rescuing captured damsels is fine and all, it's already overused everywhere and I'd prefer to not start (continue) (over)doing it in my campaign. Easy solution would be to just make her a dude and keep the general obsessive creepiness of the situation, but any other ideas?
Maybe plant a few clues indicating she's there, but is in fact a monster or agent of evil? All the wile keeping her as she is. Perhaps she is under a curse that makes her register as being evil.
